日(ri)前，國(guo)網天(tian)津(jin)市(shi)(shi)電(dian)力公司提出的“以電(dian)供(gong)(gong)熱”試點規劃，被寫入(ru)天(tian)津(jin)市(shi)(shi)政府(fu)工(gong)作(zuo)報告(gao)，預(yu)示著(zhu)天(tian)津(jin)市(shi)(shi)加(jia)熱電(dian)纜的需求量將(jiang)不斷提高。“推(tui)廣電(dian)能替(ti)(ti)代(dai)工(gong)程，啟動以電(dian)供(gong)(gong)熱試點”被寫入(ru)天(tian)津(jin)市(shi)(shi)政府(fu)工(gong)作(zuo)報告(gao)，這標(biao)志(zhi)著(zhu)天(tian)津(jin)電(dian)能替(ti)(ti)代(dai)工(gong)作(zuo)已進入(ru)政府(fu)主導、系(xi)統推(tui)進的新(xin)階段(duan)。

當前電能替代(dai)技術成(cheng)(cheng)(cheng)熟，經濟優勢明顯，清(qing)潔環保(bao)已成(cheng)(cheng)(cheng)為政府和(he)廣大(da)用戶的共識。一直以(yi)來，北方地區(qu)冬季(ji)供(gong)熱(re)取暖主要是采用燃煤鍋爐，造(zao)成(cheng)(cheng)(cheng)嚴重大(da)氣污(wu)染。如(ru)果采取電能替代(dai)，以(yi)電能或太陽(yang)能代(dai)替燃煤蒸汽供(gong)熱(re)，不但供(gong)熱(re)成(cheng)(cheng)(cheng)本大(da)幅度降低，而且不會(hui)造(zao)成(cheng)(cheng)(cheng)環境污(wu)染。

在有些專家看(kan)來(lai)，電能(neng)作(zuo)為清潔(jie)能(neng)源的優勢凸顯，替(ti)(ti)代(dai)潛(qian)力巨大。4月2日，國(guo)家電網(wang)公(gong)司召(zhao)開了2015年電能(neng)替(ti)(ti)代(dai)工(gong)作(zuo)推(tui)(tui)進會，發布了《國(guo)家電網(wang)公(gong)司2015年全(quan)面深入推(tui)(tui)進電能(neng)替(ti)(ti)代(dai)行(xing)動(dong)計劃》，提出(chu)了確保全(quan)年完(wan)成650億千(qian)瓦(wa)(wa)時、力爭實現750億千(qian)瓦(wa)(wa)時替(ti)(ti)代(dai)電量。

據了解，今年(nian)國(guo)家電(dian)(dian)(dian)(dian)網(wang)公司將著(zhu)力(li)鞏固擴大電(dian)(dian)(dian)(dian)窯爐、電(dian)(dian)(dian)(dian)鍋爐、熱(re)泵等(deng)(deng)(deng)成熟項目的實(shi)施范圍，因地(di)制宜(yi)拓展新(xin)領域、推廣新(xin)技術，除在(zai)港口(kou)地(di)區推廣岸電(dian)(dian)(dian)(dian)替代(通(tong)過(guo)電(dian)(dian)(dian)(dian)纜將船舶(bo)用電(dian)(dian)(dian)(dian)與(yu)岸上電(dian)(dian)(dian)(dian)源(yuan)(yuan)連接，在(zai)船舶(bo)靠岸期間采(cai)用陸地(di)電(dian)(dian)(dian)(dian)源(yuan)(yuan)供電(dian)(dian)(dian)(dian))外，還(huan)將對居民區、學校等(deng)(deng)(deng)用戶推廣碳晶、電(dian)(dian)(dian)(dian)熱(re)膜、發熱(re)電(dian)(dian)(dian)(dian)纜等(deng)(deng)(deng)技術，在(zai)企事(shi)業單位(wei)食堂推廣電(dian)(dian)(dian)(dian)磁灶(zao)、電(dian)(dian)(dian)(dian)蒸鍋，在(zai)油田推廣電(dian)(dian)(dian)(dian)動鉆機，在(zai)油氣輸送(song)管線推廣電(dian)(dian)(dian)(dian)力(li)加壓等(deng)(deng)(deng)。

從(cong)消(xiao)費端來(lai)看，各地(di)主要通過以電(dian)代煤(mei)、以電(dian)代油(you)來(lai)促進節(jie)能減(jian)排(pai)。北京市城六區基本取消(xiao)燃(ran)煤(mei)鍋爐，農村地(di)區新增減(jian)煤(mei)換煤(mei)120萬(wan)噸。河(he)北省提出大(da)幅壓減(jian)煤(mei)炭用量(liang)，實施煤(mei)電(dian)節(jie)能減(jian)排(pai)升級改造(zao)行(xing)動(dong)計劃(hua)。在歐美發達國(guo)(guo)(guo)家(jia)，電(dian)采暖(nuan)普及率非常高，美國(guo)(guo)(guo)80%的城市實行(xing)電(dian)采暖(nuan)，加拿大(da)、德國(guo)(guo)(guo)、法(fa)國(guo)(guo)(guo)等(deng)電(dian)采暖(nuan)比例均在50%以上(shang)。

有專(zhuan)家分析認為，國內大力開展電(dian)能(neng)(neng)(neng)替(ti)代(dai)，能(neng)(neng)(neng)有效緩解電(dian)纜(lan)(lan)產(chan)(chan)業產(chan)(chan)能(neng)(neng)(neng)過(guo)剩(sheng)(sheng)帶來的(de)巨(ju)大壓力。國內電(dian)線(xian)電(dian)纜(lan)(lan)行業產(chan)(chan)能(neng)(neng)(neng)過(guo)剩(sheng)(sheng)以及設(she)(she)備過(guo)剩(sheng)(sheng)是不爭的(de)事(shi)實，產(chan)(chan)能(neng)(neng)(neng)過(guo)剩(sheng)(sheng)意味(wei)著供(gong)大于求(qiu)，意味(wei)著惡(e)性競爭;而設(she)(she)備過(guo)剩(sheng)(sheng)又反(fan)映出開工率不足。事(shi)實上(shang)，僅(jin)次于汽(qi)車制造業的(de)第二大產(chan)(chan)業電(dian)線(xian)電(dian)纜(lan)(lan)行業在贏得“全球第一(yi)”之后，卻因蜂擁而上(shang)深(shen)陷“紅(hong)海”的(de)產(chan)(chan)能(neng)(neng)(neng)嚴重過(guo)剩(sheng)(sheng)之中。不足四(si)成的(de)產(chan)(chan)能(neng)(neng)(neng)開工率還不到歐(ou)美同期(qi)一(yi)半，連(lian)續萎靡的(de)虧損包袱成為不少上(shang)市公司(si)不能(neng)(neng)(neng)承受之重，欲剝離減負。

近來研發成功的(de)碳纖維(wei)加熱(re)電(dian)(dian)纜，將加熱(re)電(dian)(dian)纜系統的(de)應(ying)用(yong)推(tui)向了技術創(chuang)新階段。推(tui)行(xing)“以電(dian)(dian)供熱(re)”的(de)應(ying)用(yong)，廣泛(fan)涉及千家(jia)萬戶。例如在住宅內(nei)部，可實現(xian)墻(qiang)壁、地板、空(kong)間加熱(re)。其中，僅墻(qiang)壁和(he)地板加熱(re)系統，就需(xu)要大量加熱(re)電(dian)(dian)纜。此外(wai)，根據外(wai)國經驗，道路和(he)機場融雪加熱(re)，也普遍(bian)首(shou)選加熱(re)電(dian)(dian)纜系統。

電(dian)(dian)(dian)采(cai)暖(nuan)相比(bi)燃(ran)煤采(cai)暖(nuan)優(you)勢比(bi)較明顯(xian)。當前，國(guo)(guo)內電(dian)(dian)(dian)力(li)(li)(li)(li)供(gong)(gong)需矛(mao)盾將日趨(qu)緩和，2006年中國(guo)(guo)電(dian)(dian)(dian)力(li)(li)(li)(li)供(gong)(gong)需基本(ben)(ben)平(ping)衡。從2007年開始，一部分煤炭(tan)產地(di)為降低煤炭(tan)運輸(shu)成本(ben)(ben)，大(da)力(li)(li)(li)(li)發(fa)展火力(li)(li)(li)(li)發(fa)電(dian)(dian)(dian)，變(bian)煤炭(tan)運輸(shu)為電(dian)(dian)(dian)力(li)(li)(li)(li)輸(shu)送(song)，并且(qie)國(guo)(guo)家正在大(da)力(li)(li)(li)(li)發(fa)展風力(li)(li)(li)(li)發(fa)電(dian)(dian)(dian)、太陽能發(fa)電(dian)(dian)(dian)、水力(li)(li)(li)(li)發(fa)電(dian)(dian)(dian)、核(he)電(dian)(dian)(dian)等，電(dian)(dian)(dian)力(li)(li)(li)(li)已出(chu)現冬季過剩(sheng)現象(xiang)，這就為電(dian)(dian)(dian)采(cai)暖(nuan)提供(gong)(gong)了(le)足(zu)夠空間。

據相關統計(ji)數字表明，我國地面(mian)輻射采暖市(shi)場在(zai)2010年(nian)底已(yi)達千億元，其(qi)中(zhong)技術成熟的低溫(wen)熱水輻射采暖和散(san)熱片(pian)采暖占(zhan)據70%以上的市(shi)場份(fen)額。電(dian)采暖雖(sui)處于起(qi)步階(jie)段，但也占(zhan)據了(le)25%左右的市(shi)場份(fen)額，并(bing)且保(bao)持(chi)持(chi)續上升的趨勢。

如(ru)今，全國各地(di)針對電(dian)(dian)采(cai)暖紛(fen)紛(fen)出臺優惠政策，這從側(ce)面(mian)展現(xian)出了(le)電(dian)(dian)采(cai)暖的(de)巨大潛力，也(ye)為碳纖(xian)維(wei)發(fa)熱電(dian)(dian)纜的(de)發(fa)展提供(gong)(gong)了(le)無限(xian)的(de)可能(neng)性。就(jiu)目前各個集中(zhong)(zhong)供(gong)(gong)暖區域推出的(de)供(gong)(gong)暖政策來看，煤炭供(gong)(gong)熱的(de)時(shi)代正在成為歷史。而新型(xing)的(de)環保節能(neng)的(de)采(cai)暖方(fang)式正在占(zhan)領市(shi)場，其中(zhong)(zhong)電(dian)(dian)采(cai)暖以其成熟的(de)行業體系和卓越的(de)供(gong)(gong)暖效果正在不(bu)斷受到重(zhong)視。這為正處于產能(neng)過剩的(de)電(dian)(dian)纜產業開辟了(le)一個新的(de)市(shi)場。
